Solution Overview
Problem
Current biological assays using bulk reactions lose significant information about individual molecular interactions and activities, as they average data across multiple reactions, making it difficult to analyze specific interactions and effects on therapeutically relevant pathways.
Innovation Solution
The development of methods and systems for single-molecule, real-time analysis using optical confinement techniques like zero mode waveguides, allowing for the monitoring of interactions between immobilized and non-immobilized reaction components with high spatial and temporal resolution, enabling the detection of binding events and characterization of reaction kinetics at the single-molecule level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If bulk reactions are used for biological assays, then general trends of biological reactions can be ascertained, but substantial information about individual molecular interactions is lost
Solution Approach 1:
The patent divides the bulk reaction system into individual molecular reaction sites, allowing separate monitoring of each molecular interaction. By segmenting the analysis into single-molecule events, the system preserves information about individual interactions while maintaining manageable complexity through standardized detection protocols
Solution Approach 2:
The patent transitions from bulk (macroscopic) measurement to single-molecule (microscopic/nanoscale) measurement, adding a spatial dimension of resolution. This dimensional change enables observation of individual molecular events that are averaged out in bulk measurements, thereby reducing information loss
2Measurement precision
If single-molecule analysis is implemented, then detailed insights into individual molecular interactions are obtained, but the complexity of the system increases
Solution Approach 1:
The patent introduces optical confinements as intermediary structures that facilitate single-molecule observation. These confinements act as mediators between the molecular interactions and the detection system, enabling high-precision measurement while managing system complexity through a standardized intermediary platform
Solution Approach 2:
The patent replaces complex mechanical manipulation systems with optical detection methods. By using optical confinements and fluorescence detection instead of mechanical handling of individual molecules, the system achieves high measurement precision while reducing mechanical complexity
3Ease of operation
If bulk reaction monitoring is used, then data collection is simplified, but the ability to identify specific interaction factors is reduced
Solution Approach 1:
The patent segments the data collection process into individual molecular interaction events, allowing specific interaction factors to be identified while maintaining ease of operation through automated single-molecule detection and analysis protocols
4Productivity
If averaging of bulk reaction results is performed, then general trends are identified, but information about individual molecular complexes is lost
Solution Approach 1:
The patent transitions from bulk averaging (macroscopic) to single-molecule resolution (microscopic), adding a resolution dimension that preserves information about individual molecular complexes while maintaining productivity through high-throughput single-molecule analysis
